The P72x high impedance differential protection series provide independent and simple high impedance differential protection for generator, reactor, motor and busbar applications where fast clearance of faults is required.

As well as offering the same application benefits as traditional high impedance electromechanical protection schemes, it combines the added benefits of numerical technology to provide advanced communications, event records, fault records, disturbance records and ancillary protection features.

Combined with the P79x, a standalone metrosil and resistor unit, it provides simplified scheme engineering for single or three-phase differential applications.
